Plus I'll tell you exactly how I felt when I first read this, so my comments in bold:

A beauty treatment ended in the emergency room for a Chinese man who bathed in live eels after one of the slippery creatures swam inside his penis.

Me: WTF?

Vain Zhang Nan, from Hubei province, central China, had heard that bathing with young eels would make him look younger because they would chew off dead skin.

Me: Ok, never heard of such a treatment, but hey it could be effective.

But the 56-year-old got more than he bargained for when he climbed into the bath with the animals.

"I felt a severe pain and realised a small eel had gone into the end of my penis," Mr Zhang said.

Me: Oh no, no way *cringes*, how is this even possible?

"I tried to hold it and take it out, but the eel was too slippery to be held and disappeared."

Me: *Crosses legs* OHHHHH AHHHH ouchhhhhhh *grips onto pillow*.

Mr Zhang was taken to hospital and underwent a three hour operation to remove the eel, which measured about 1.2cm wide and 15cm long, and was dead when doctors found it inside his bladder.

Doctor Jin Wang said the eel's slimy body had worked as a lubricant.

"The diameter of the urethra in a man's genitals is just a little narrower [than the eel], but because eels are quite slippery, its body worked as a lubricant so it got into the penis smoothly," he said.

Me: Please stop, you are not helping Mr. Doctor, I can't take this anymore *goes into fetal position*.

Oh and if you wanted to see the size of the eel, or its state after the incident:

So everyone, what do you think about all this, and how did you feel reading this, specially guys, like myself?

I was thinking of asking something similar but thought it would be a bit too childish, but now that you have brought it up, omg I don't think I want to even imagine that kind of scenario, its like something from one of those crazy hentai
